In Pokémon Black and White, he is attempting to arrest the Seven Sages of Team Plasma. He appears in the player's house, disguised as their mother, requesting their help to find the sages. After he has successfully arrested all of the sages except Ghetsis, he heads off to confirm information he has received about N and his dragon Pokémon being in a distant region.

In Pokémon X and Y, Looker is temporarily stationed in Lumiose City in the Kalos region while investigating Xerosic and Team Flare, under the guise of a private detective opening up a new detective bureau, the Looker Bureau. After he succeeds in arresting Xerosic, he leaves Lumiose City behind to escort Xerosic to his trial.

In Unlocking the Red Chain of Events!, Looker infiltrated the Fuego Ironworks disguised as a Galactic Grunt in order to find out what Team Galactic was doing there. Despite this, he was discovered and thrown in a cell until Ash and his friends rescued him. By this time, Team Galactic had already fled but Looker found a piece of the Red Chain. Taking it back to the Floaroma Police Station, the Floaroma Police set up a live transfer of the scanned data to International Police HQ. However, the piece had been engineered by Charon to blow up the scanner and wipe all data from the International Police database.

After a long absence, Looker finally appeared again in Team Plasma's Pokémon Power Plot!, where he disguised himself as a Hiker. After revealing himself to Ash and his friends, Looker explained that he had come to Unova in order to investigate the actions of Team Plasma, who were planning to take over the region. After an encounter with several Team Plasma members, including the Plasma Scientist Colress, he left the group to continue his investigation.

Looker again met Ash and his friends in Team Plasma's Pokémon Manipulation! at a city, where a Haxorus was going on a rampage. Looker realized that it must be under the same kind of control as the Pokémon from before, and attempted to use his barrier-creating device to stop Haxorus from being controlled, without any result. He then used an energy indicator to find the source of the energy that controlled Haxorus, eventually pinpointing it into Team Plasma's helicopter.

In Ash and N: A Clash of Ideals!, he disguised himself as Cedric Juniper's assistant and escorted Ash and his friends to the White Ruins. Later, when Team Plasma attacked in an attempt to find the Light Stone, he unmasked himself and began trying to fight the villains. He also appeared in Team Plasma and the Awakening Ceremony! and What Lies Beyond Truth and Ideals!, where he wound up getting caught along with Iris, Cilan, and Cedric Juniper, but they later freed Looker. He then managed to convince Team Rocket into joining the battle. Eventually, when Reshiram was freed from Team Plasma's control, Looker arrested all the Team Plasma members, effectively putting an end to the team's existence.

Looker and Lack-Two are both equipped with various gadgets called the "International Police Arms". While Looker's gadgets fail on him either from being cheaply made or for physical comedy at Looker's expense, Lack-Two is able to use them just fine. Each of the Arms are labeled by number in order of appearance.

Excellent Scope (Japanese: エクセレントスコープ): a pair of goggles that are designed to work as binoculars. In the Black & White chapter, Looker is seen using a different version after his original pair broke called the Excellent Scope Revised (Japanese: エクセレントスコープ改).

Invisible Cloth (Japanese: インビジブルクロース): a sheet that can blend into the background of something. Depending on how it's held, the cloth can either hide the user perfectly or not hide them at all.

Record Bubble (Japanese: レコードバブル): a microphone that releases bubbles when spoken into. The bubbles go to the target and pop, which releases the message recorded inside.
